SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Context windows are finite; this skill provides techniques to extend effective context capacity through compression, masking, caching, and partitioning to maintain signal with fewer tokens.

Core Features & Use Cases

  • KV-cache optimization: Structure prompts to maximize prefix stability so repeated requests reuse cached tokens, reducing cost and latency.
  • Observation masking: Replace verbose tool outputs with compact references while keeping the ability to retrieve full content later.
  • Compaction: Summarize older context when utilization approaches limits, preserving decisions and critical state.
  • Context partitioning: Split work across sub-agents when a single window cannot hold the full problem, coordinating results to produce a final answer.
  • Use Case: Long-running agent systems that handle large documents or multi-turn conversations with strict budget constraints.

Quick Start

Enable KV-cache optimization, masking, compaction, and partitioning in that order, then monitor token usage and performance.

FAQPage Schema
How do I reduce token usage in long-running AI agent sessions?▼

Reduce token usage in long-running AI agent sessions by applying context optimization techniques like KV-cache optimization, observation masking, compaction, and context partitioning to maintain signal with fewer tokens.

What is context partitioning and when do I need it for multi-turn conversations?▼

Context partitioning splits work across sub-agents when a single window cannot hold the full problem, coordinating results to produce a final answer. It is needed for multi-turn conversations exceeding context limits.

How do I maximize prefix stability to reuse cached tokens and reduce latency?▼

Maximize prefix stability to reuse cached tokens by structuring prompts for KV-cache optimization, ensuring repeated requests reuse cached tokens to reduce cost and latency in AI agent sessions.

Does observation masking work for replacing verbose tool outputs with compact references?▼

Observation masking works by replacing verbose tool outputs with compact references while keeping the ability to retrieve full content later, effectively reducing token usage in document-heavy tasks.

What is the best way to summarize older context when approaching token limits?▼

The best way to summarize older context when approaching token limits is compaction, which summarizes older context while preserving decisions and critical state to extend effective context capacity.

Can I configure budgets and thresholds for context compaction and partitioning?▼

You can configure budgets and thresholds for context compaction and partitioning to manage strict budget constraints in long-running agent systems handling large documents or multi-turn conversations.
